Zernio

What is Zernio?

Zernio is the marketing infrastructure 200,000 developers build products on. We absorb the integrations, platform approvals and maintenance behind every channel, all on official APIs, so you can start building today. One API covers 16 social platforms, ads on 7 networks, WhatsApp, iMessage, and phone numbers with calls and SMS that you buy inside Zernio. Use the REST API in your code, or let your coding agent do the same through our MCP server and CLI.
